DOOR-CHECK.

SPECIFICATION forming part Of Letters liatent NO. 436,809, datedSeptember 23, 1890.

Application filed March 29, 1890. Serial No. 345,922- (Model) To allwhom it may concern:

Be it known that I, WILLIAM SHIPSEY, a citizen of the United States,residing at San Luis Obispo,in the county of San Luis Obispo and Stateof California, have invented certain new and useful Improvements in DoorBuffers and Holders, of which the following is a description.

This invention has relation to an improvement in door-stops of thatclass which are pivotally connected to the floor in the path traversedby the free end of the door, between the ends of which said door takes,thereby swinging the holder into a position in which the door isembraced loosely by the holder. By reason of the fact that the holder isswung to the embracing position it is necessary that the distancebetween the stops at the ends of the holder must be greater than thewidth of the door. Hence it follows that when the holder is in theembracing position the door is subject to short vibrations to and frobetween the stops, as occasioned by the wind. By my invention I proposeto avoid these disagreeable vibrations and consequent tugging of thedoor in its efforts to escape, so that when once fastened the door willremain in position and be noiseless.

With the above objects in view the invention consists in certain detailfeatures hereinafter specified, and particularly pointed out in theclaim.

Referring to the drawings, Figure 1 is a diagrammatic view of a door,the adjacent portion of the floor, and a stop arranged in position andconstructed in accordance with my invention. Fig. 2 is a plan of thestop in detail, the same being enlarged. Fig. 3 is a side elevation.

Like numerals indicate like parts in all the figures of the drawings.

2 designates a door adapted to open in this instance to the left.

3 designates the floor over which the door travels, the line of travelbeing indicated by the dotted line 4.

Near the mop-board I locate the hereinafter-described andbeforennentioned stop. This stop may be formed of either wood or metal,and consists of simply a block of oblong shape termin ating near itsends in opposite shoulders or stops. The rear stop 5 is abrupt or at aright angle to the lower edge of the block, while the front stop 6 isgradual or provided. with an inclined face 7, its upper end extending toabout the central portion of the intermediate recess 8, formed by thetwo shoulders.

In rear of the shoulder 5 and at each side of the longitudinal center ofthe stop I form vertical openings 9, either one of which is adapted toreceive a screw or bolt 10, the lower end of which passes into thefloor. In the present instance, wherein the device is employed inconnection with a door that opens to the left, the screw 10 is passedthrough that opening 9 located at the left of the stop. The parts beingmounted in position as shown that is, the screw 10 being inserted in thefloor about on the dotted line eL-the following operation takes place:The door being opened, its advance corner rides into the recess 8 andagainst the free end of the shoulder 5, thus swinging the free end ofthe stop-that is, the shoulder 6toward the door, so that the oppositesides of the door are embraced by the shoulders 5 and 6. The verticalshoulder 5 prevents the door from passing beyond the same, and anypressure upon the door toward said shoulder acts only to swing the stopfarther around, so that the incline face 7' of the shoulder 6 takesunder and binds against the edge of the door, and in this manner thedoor is automatically and securely wedged against any movement whateveruntil the same is released by an outward swing of the stop, which may beaccomplished by the foot of the operator.

Having described my invention, what I claim is- The improved door-stopherein described, the same consisting of an oblong block havin g atransverse recess forming opposite front and rear shoulders, the lattershoulder having an inner inclined face, said stop in rear of the rearshoulder and at each side of its longitudinal center provided with ascrewreceiving opening, substantially as specified.
